Giordano Bruno Quotes
In space there are countless constellations, suns and planets; we see only the suns because they give light; the planets remain invisible, for they are small and dark. There are also numberless earths circling around their suns.
Bruno, Giordano. On the Infinite Universe and Worlds. Translated by Dorothea Waley Singer, in Giordano Bruno: His Life and Thought, Henry Schuman, 1950, p. 304.
Giordano Bruno was an Italian Dominican friar, philosopher, mathematician, poet, cosmological theorist, and Hermetic occultist. He is known for his cosmological theories, which conceptually extended the then-novel Copernican model. He proposed that the stars were distant suns surrounded by their own planets, and he raised the possibility that these planets might foster life of their own, a cosmological position known as cosmic pluralism. He also insisted that the universe is infinite and could have no "center".
